SPECIFICATION forming part of Letters Patent No. 401,708, dated April16, 1889.

Application filed August 24, 1888. Serial No. 283,632- (No model.)Patented in England August 20, 1888, No. 10,688 in France May27, 1887,No. 183,853, and in Italy August 8, 1887,1Io. 22,144.

To all whom it may concern.-

Be it known that I, HIRAM STEvENs MAXIM, mechanical engineer, a citizenof the United States of America, and a resident of London,

England, have invented new and useful Improvements in Eyeleting andRiveting Machines, (for which I have obtained patents in the followingcountries: Great Britain, No.

10,686, hearing date August 20, 1886; France,

to No. 183,853, bearing date May 27, 1887, and

Italy, No. 22,144, dated August 8, 1887,) of

which the following is a specification, reference being had to theaccompanying drawlugs.

My invention relates to machines which are chiefly designed forperforating cloth, leather, or other materials, inserting eyeletstherein, and riveting or clinching the said eyelets. My improvedmachines are, however, applica- 2o ble for similar purposes-such as thesecuring 0f rivets in leather or other materials.

One object of my said invention is to provide for piercing or punchingthe cloth, leather, or other material and inserting an eyelet or groupof eyelets therein by one operation. For this purpose, whenthe materialis to be pierced Without removing or cutting pieces therefrom, I employpointed pins or studs upon which the eyelets are to be placed, and tubesor tubular dies which slide upon the said pins or studs and force thecloth, leather, or other material thereon, pressing it closely againstthe flanges of the said eyelets. These pointed pins or studs are veryadvan tageous for perforating cloth or other woven fabrics, as theyeffect this operation without liability to injury of the threads andconsequent weakening of the said fabrics. IV hen pieces are to be cut orpunched out of the ma terial to admit the eyelets, I substitute for thesaid pointed pins or studs tubular punches adapted to enter theaforesaid tubes or dies.

Another object of my said invention is to provide for the simultaneousinsertion of two or more eyelets in any desired relative p0sitions. Forthis purpose I arrange two or more of the said pins, studs, or punches,and tubes or dies in groups, as required, and pro vide means foroperating the same simultaserted in the cloth or. other material.

I also pro neously, as hemeinaft-er set forth.

vide for simultaneously riveting or clinching two or more eyelets.

My said invention, moreover, comprises an adjustable gage for regulatingthe distance between the eyelets or groups of eyelets in- It alsocomprises various other improvements, hereinafter described.

In the accompanying drawings I have shown how my said invention may beconveniently and advantageously carried into practice.

Figure 1 is a side elevation, and Fig. 2 a rear elevation, of one formof my improved machine. Fig. 3 is a vertical central section on the lineas 00, Fig. 1, and Fig. 4: a vertical central section on the line 00'50, Fig. 2, both drawn to an enlarged scale, showing a portion of thesaid machine. Fig. 5 is a horizontal section on the line 00 a Figs. 3and 4E; and Fig. 6 is a vertical section 011 the line on 00 Figs. at and5.

A is a standard or post which is to be secured to the floor of a room orto any other suitable support.

Bis a disk or head which is supported upon 7 5 the top of the saidstandard.

O is a vertical rod or shaft, which has a tube, D, fitted thereon andheld in place by means of a collar, 0 secured upon the rod or shaft 0 bya pin, 0*, passing through the same and through the said tube, so that,although the said tube is capable of rotation upon the said shaft, itwill participate in any endwise movement thereof. The rod or shaft 0 andtube D are arranged to slide up and downin the projecting part or boss Aof the standard A and in the disk or head B.

E is another disk or head which is screwed upon the upper end of thetube D, and is securely held in place thereon by means of the nut O. Thevertical rod or shaft 0 is coupled at its lower end, by means of a link,F, to a forked lever or treadle, G, which is pivoted at G to thestandard or post A, the two parts of the forked end of the said leverpassing through slots A in the said standard. By means of the said leveror treadle the upper disk, E, may be moved downward to insert theeyelets or to rivet or clinch the same, as hereinafter described. A pinor rod, E, is too fixed in the disk E, and works in ahole, B, in thedisk B, so that, although the disk E is free to move toward and awayfrom the disk B, it will rotate therewith, as and for the purposehereinafter specified. The shaft 0 is provided with a spring, H, forraising the same and the disk E when the treadle G is released.

I I are the pointed pins or studs for piercing the cloth or othermaterial. These pins or studs are fixed in the disk B in a radial lineequidistant from each other. K K are the tubes or tubular dies forforcing the material upon the said pins or studs I and upon the eyeletsplaced thereon. These tubes or tubular dies are fixed in the disk Eabove the pins or studs 1. The said tubes or dies are slitlongitudinally, so that they will expand when forced down upon the saidpins or studs and upon the eyelets thereon. They will, therefore, at alltimes during their movement upon the said pins or studs fit closelyaround the same or around the eyelets thereon, and will consequently actvery efficiently in pressing the material down against the flanges ofthe said eyelets. The lower ends of the said tubes or dies arepreferably serrated or roughened, as shown, to increase their hold uponthe material.

L is a plate in which are fixed two pins or rods, L. These rods arefitted to slide vertically in holes in the disk B, in which they areretained by means of collars L secured upon them by means of screws LTwo springs, L are inserted in recesses or cavities B in the disk B, sothat they support the plate L in the position shown. The said plate ismade with holes L through which extend the pins or studs 1. The objectof this springplate is to push the material with the eyelets therein offthe said pins or studs as soon as the treadle G is released.

M is an adjustable gage, which is attached to the plate L, for thepurpose hereinafter specified. This gage is secured to the said plate bymeans of screws M, passing through slots M therein, so that it can beadjusted toward or away from the pins or studs 1. The said gage consistsof a plate provided with pins or studs M so situated that when the clothor other material has been perforated and a group of eyelets insertedtherein the said eyelets can be placed upon the said pins or studs lVP,and the material will then be in the proper position to be againperforated and to have another group of eyelets inserted therein. Bythese means the insertion of the groups of eyelets at regular intervalsor at equal distances apart is effectually insured.

To prevent the lifting of the material off the eyelets by the tubes ortubular dies K in their upward or return movement, a spring plate orguard, N, is attached to the upper piercing or perforating the materialand insertin g the eyelets therein, and will then by their reactioncause the plate N to force the material away from the said tubes or diesK. The plate N is made with holes N through which the said tubes or dieswill pass in the operation of the machine.

0 O are anvils, which are firmly secured in the outer ends of recessesor cavities B in the lower disk, B, and through which extend pins orrods 0, provided with heads or flanges O Springs 0 are placed in therecesses or cavities B which springs hold the said pins or rods in theposition shown.

P P are dies, which are firmly fixed in the upper disk, E, and areprovided with pins or studs P, adapted to enter the central holes in theanvils O, as and for the purpose hereinafter specified.

Q R are other anvils fixed in the lower disk, B, and S T are dies orhammers for operating in combination with the said anvils,,

as and for the purposes hereinafter specified.

In the apparatus shown in the drawings the different sets of tools forperforating the material and inserting the eylets therein and forriveting or clinching the said eyelets are arranged radially, each setbeing at right angles to the adjacent sets. Therefore, by rotating thedisks B E upon the shaft 0 through an angle of ninety degrees after thematerial has been perforated and a group of eyelets inserted therein thenext set of tools for riveting or clinching the eyelets may be broughtinto suitable proximity to the operator to enable him to readily subjectthe eyelets to the action of the said tools.

A spring-catch is preferably arranged in combination with the lower diskor head, B, to facilitate the adjustment of the disks B E and to retainthem in any desired position. This catch may consist of a forked rod, U,carrying an anti-friction roller, U, and fitted to slide in a tube ortubular casing, U secured in a recess or cavity in the table or platformV, which is supported upon the standard A and encircles the disk B. A

spring, U is placed in the tube or casing U and acts upon the roller U,so that when the said disk is in either of its operative positions thesaid spring will cause the roller U to enter the corresponding notch,Bin the disk B.

A circumferential groove, B is formed in the disk B, and a guide-piece,W, is secured to the standard A and projects into the said groove, sothat although the said disk is free to rotate yet upward movementthereof is prevented, thus obviating any liability to lifting of thesaid disk should the dies K stick upon the pins or studs I.

Y is a spring-catch for holding down the plate L while the upper disk,E, is repeatedly moved up and down to force the material properly uponthe eyelets. This catch Y is pivoted at Y upon a screw fixed in thetable V, and is acted upon by a spring, Y whereby it is held in theposition shown. It has an inclined surface at Y so that when the plate Lis depressed it will force the said catch outward, and the said catchwill then spring over the top of the said plate L, and will hold downthe same. The said catch is provided with a handle, Y, whereby it may bedisengaged from the plate L when required. This catch is not in allcases necessary, and may be dispensed with if desired.

The operation of the improved machine above described is as follows-thatis to say, the disks B E are first so adjusted that the perforators orpunches I are next the operator. Eyelets are then placed upon the saidperforators, and the cloth or other material is placed in the desiredposition thereon. The treadle G is then rapidly depressed by the foot,so as to move the disk E downward. In this downward movement the dies Kforce the material upon the perforators or studs I and upon the eyeletsthereon, the springs N yielding to permit the necessary upward movementof the plate N relatively to the disk E, and the springs L yielding topermit the depression of the plate L. The catch Y then engages with thesaid plate and holds the same down, so that the treadle may, ifnecessary, be operated repeatedly to drive the material home upon theeyelets. Vhen the treadle is released, the spring H, by its reaction,raises the disk E, and when the catch Y is disengaged from the plate Lthe springs L react and cause the said plate to rise and force theeyelets upward upon the said pins or studs I, so that the material, withthe eyelets therein, may be easily removed from the said pins or studs.The material, with the eyelets therein, is then lifted, and the disks BE are rotated through an angle of ninety degrees to bring the anvils Oand dies P next the operator. The eyelets are then placed upon the pinsor rods 0', and the disk E is again depressed by means of the treadle G.In this downward movement of the said disk the pins or studs P come incontact with the pins or rods 0, push the said pins or rods downward andenter the holes in the anvils O. The eyelets are then clinched orriveted by pressure or by impact between the dies P and the anvils O.

In some instances the cloth or other material is driven home orcompressed upon the eyelets by means of the anvils R and the dies T, andthe said eyelets are partially clinched by means of the anvils Q and thedies or hammers S, and the eyelets are then subjected to the action ofthe anvils O and dies P to complete the clinching or riveting of thesaid eyelets.

I sometimes so construct the machine" that the riveting or clinching ofone eyelet or group of eyelets will be effected simultaneously with theinsertion of another eyelet or group of eyelets. In this case thevarious tools or sets of tools, instead of being arranged row or seriesat equal distances apart, and the heads in which the said tools arefixed do not rotate. The adjustable gage above described is notrequired, as the pins or projections of the riveting or clinching toolsserve as a gage for insuring the uniform spacing of studs and the metal.plate or strip is placed thereon, the cloth or other material is thenlaid upon the said pins or studs, and the upper disk or head isdepressed to perforate the material and force the same upon the eyelets.

Another metal plate or strip is sometimes placed upon the eyelets beforeriveting or clinching the same.

My improved machine is especially advantageous Where strips of leather,canvas, cloth, or other material have to be secured together at regularintervals by groups of two or more eyelets, either with or withoutstiffening plates or strips of metal or other material. The said machineis moreover useful in cases where single eyelets are to be inserted inleather or other materials, and by inserting suitable tools in theaforesaid disks or heads it may be readily adapted for inserting andsecuring small rivets in such materials.

It is not essential that the perforating and riveting or clinchingdevices should be carried by disks, as above described. They may, ifdesired, be otherwise suitably arranged for the purposes of myinvention.
